I Built a Free JSON Formatter & Validator Tool — Here’s Why and How

Posted on by — No Comments ↓

Hey Devs! 👋

I’ve been working on a side project that I personally needed quite often — a clean, fast, and mobile-friendly JSON Formatter + Validator.

There are many tools out there, but most either show too many ads, lag on mobile, or ask for sign-in.

So I built this one:

🌐 https://quick-json.web.app

🧠 Why I Built It:

As a frontend developer, I constantly deal with APIs, and copying/pasting messy JSON was frustrating.

I just wanted something that:

  • Works instantly
  • No sign-up or clutter
  • Formats + Validates JSON
  • Mobile responsive (because I debug from phone too!)

🔧 Tech Stack:

  • Angular (frontend)
  • Firebase Hosting
  • TypeScript
  • SCSS for styling

It’s hosted on Firebase’s free tier and loads pretty fast.

✅ Features:

  • Paste raw JSON → get beautified output instantly
  • JSON validation included
  • Auto-highlight invalid structures
  • 100% free, no ads

📌 Try it out here:

💬 I’d Love Feedback

This is my first full project after recently joining a new company & getting married (yes, it’s been a wild year!). 😄

Please let me know:

  • What can I improve?
  • Any cool features you’d love to see?
  • Do you use similar tools?

Thanks for reading — I’d truly appreciate any suggestions or thoughts! 🙌

Happy coding!
